    Monte, I'm guessing this is going to be a singles class...so that knocks aprilia out of it. And Mongo said that the front end had to come from the same manufacturer as the dirtbike, since KTM (or Husky)doesn't have any full fledged sportbikes I'd say that'd be a hard rule to conform to for them.

    :(

    Would other manufacturers be elligible as well??? e.g. KTM they have the Super Duke, which I believe would be a plenty competent front end for one of these guys.

    So the answer is actually no, you haven't run a stock one. Thanks but my response is the same as to everyone else wanting to say stock won't last - until that is proven, we're going with stock thanks.

    Aftermarket, not sure exactly what, the ones on them now are some Roland designed and made.

    Good lord will you guys chill - seriously. You're making assumptions based on what I told you flat out was NOT all of the information.

    There is no reason why a KTM won't work - but we haven't talked about it or checked out what will work with the KTM chassis.

    You guys ALL need to relax.

    That wouldn't make sense as a spec class the way I'm reading Sean's intentions. I also think a real GP bike will crush one of these abominations. I can't even imagine what the operating costs will be on one of these diesels.

    Tdub Say what???

    No, the answer is actually yes. I have rebuilt many(many, many) stock MX motors being raced in MX, DT, and SM(no sustained high rpm) and the absolute most common failures have been valve and crank issues. Tdub

    dtalbott Driving somewhere, hauling something.

    Couldn't you lower those sustained higher RPM's by running higher gearing?

    Gearing on a roadcourse would be much different from gearing on any of the other courses (MX, SM, or flattrack), wouldn't it?

    :eek: Okay, back to the recliner for me...a fever of a 100.5 and a body that feels like I've been run over by a dumptruck means I can't even compete with Mongo when it comes to throwing my weight around. :) :D

    I suppose you could. They make peak power(stock 450 about 48) around 9K rpm, and with stock cams and timing drop 8-10 hp at 12,200. Tdub

    actually, i believe that roadracing is easier on the motor that MX and SM. MX guys like to bounce the things off the rev limiter all the damn time. roadraicng keeps a nice even load on the motor. more consitantly. either that or i build more reliable engines than you. :p

    Yea, but you're not fast enough to really strain the motor.
